I've gotten my desiredlambda issues sorted. I've seemingly gotten my idle actual AFR issues sorted. I seem to be having transient issues (and others probably.)

Tracing things back, I've narrowed it down to rk_w and then the trail turns cold. Too many routes that could be causing issues. Could anyone help with these transient issues? I'm really looking to acquire a perfectly 1 lambda at all times other than WOT and injector fuel cut.

tried FKKVS, KFKHFM, KFLF, KFVAKL, KFBAKL.

Can anyone recommend what module to even start looking in?
issues circled.

dlahi_w and dlahp_w (lambda P, I for rear O2 controller?) both turn off for these periods. Might have something to do with it? is there a way to narrow the "off range?"
